             Bug #: 30384
           Summary: Add support for network connectivity checks using
                    Network List Manager (NLM) API (Vista+)
           Product: Wine
           Version: 1.5.1
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: focht at gmx.net
    Classification: Unclassified


feature bug (for now).
There are applications that make use of Network List Manager (NLM) introduced
with Windows Vista/Windows 7 to check for network connectivity.
A symptom are messages like this in terminal:

--- snip ---
err:ole:CoGetClassObject class {dcb00c01-570f-4a9b-8d69-199fdba5723b} not
err:ole:create_server class {dcb00c01-570f-4a9b-8d69-199fdba5723b} not
fixme:ole:CoGetClassObject CLSCTX_REMOTE_SERVER not supported
err:ole:CoGetClassObject no class object {dcb00c01-570f-4a9b-8d69-199fdba5723b}
could be created for context 0x17
--- snip ---

MSDN overview:

Network List Manager:

Example applications: newer EA Download Manager versions, some EA Games
(Battlefield 3, FIFA12), Windows Live Essentials 2011

It seems plausible that they use an API that ought to be available on this
Failure doesn't seem critical, they use other means to detect network state.
Though I didn't test all of them.

This bug can serve as collector for apps that spam terminal with
"{dcb00c01-570f-4a9b-8d69-199fdba5723b}" (CLSID_NetworkListManager) messages.
Maybe there will be one where this missing functionality is actually breaking
the app.
